Yuchai is a famous engine brand in China. It is widely used in various fields such as industrial machinery, lifting equipment, vessels, electrical generator, etc. It is divided into several series, however, in this article, you will learn YC4D and YC6J these two series engine.
R&D Ability
High reliability – good cooling effect! Adopting full-flow efficient cooling lubrication system, which is capable of dealing with the high special conditions of non-road machinery with skill and ease;
1). More uniform water upstream of each cylinder; more uniform water flow field of body and cylinder cover;
2). High heat transfer coefficient of body and cylinder cover;
3). Oil cooling design with the oil temperature below 125℃;
4). Cooling system goes through CFD analysis, effectively preventing the high water temperature and improving the machine reliability;
Environmental protection and energy saving - advanced in-cylinder optimized combustion technology, easily meeting the non-road T3 emission standard, with lower fuel consumption and noise!
1). With the professional development based on the dynamic load spectrum database, low fuel consumption area completely cover the common working conditions area;
2). Yuchai patented combustion technology is featured by more sufficient combustion, fuel economy, energy saving and environmental protection;
3). With the power switching button, the corresponding external characteristics curve may be switched on according to the power requirements for light, medium and heavy working conditions to improve the fuel efficiency.
